Definitions

  • the present invention relates to an apparatus for vulcanisation and moulding of tyres for vehicles wheels and to a method of manufacturing a vulcanisation and moulding apparatus for tyres.
  • a tyre for vehicle wheels generally comprises a carcass structure including at least one carcass ply having respectively opposite end flaps in engagement with respective annular anchoring structures integrated into the regions usually identified with the name of "beads”, having an inner diameter substantially corresponding to a so-called “fitting diameter” of the tyre on a respective mounting rim.
  • a belt structure comprising one or more belt layers disposed in radially superposed relationship relative to each other and to the carcass ply, having textile or metallic reinforcing cords with a crossed orientation and/or substantially parallel to the circumferential extension direction of the tyre.
  • a tread band also made of an elastomeric material like other semifinished products constituting the tyre is applied to the belt structure,-at a radially external position.
  • respective sidewalls of elastomeric material are applied at an axially external position to the side surfaces of the carcass structure, each extending from one of the side edges of the tread band until close to the respective annular anchoring structure to the beads, which sidewalls can also be made in advance, in the form of drawn or extruded section members.
  • a vulcanisation and moulding treatment is carried out which aims at determining the structural stabilisation of the tyre through cross-linking of the elastomeric compounds, as well as at impressing the tread band with a desired tread pattern.
  • the vulcanisation and moulding treatment is carried out by introducing the green tyre into a moulding cavity of a vulcanisation and moulding apparatus, which cavity has a conformation corresponding to the outer conformation to be given to the vulcanised tyre.
  • the green tyre once enclosed in the apparatus, is pressed against the containment walls. Subsequently or simultaneously with the pressing step, heat is supplied to the tyre pressed against the containment walls.
  • suitable ridges provided on the apparatus sectors and plates give rise to formation of a desired tread pattern on the tread band of the tyre, as well as of a plurality of graphic signs on the tyre sidewalls.
  • the supplied heat causes cross-linking of the elastomeric material, of which the tyre itself is made.
  • the tread pattern is suitable for travelling on snow-covered surfaces as well.
  • a suitable series of sipes in the blocks. i.e. of a thick series of narrow cuts or hollows disposed consecutively close to each other in a circumferential direction and oriented in a way substantially transverse to the rolling direction.
  • the task of these sipes is substantially to efficiently receive and retain the snow, since it is known the snow-to-snow friction is greater than rubber-to-snow friction.
  • the mould is provided with a plurality of lamellae projecting from its inner surface delimiting the moulding cavity. These lamellae extend away from the surface itself. Typically, in tyre manufacture said lamellae are produced separately from the mould and subsequently mounted thereon.
  • the lamellae fastened in accordance with the known art have a tendency to detach themselves from the mould and get lost.
  • some of the lamellae fastened according to the known methods come off the mould, and remain entrapped in the elastomeric material of the tread and/or fall to the ground.
  • Patent US6827556B1 shows a self-locking lamella used in moulds for tyres.
  • An end portion of the lamella is inserted into a slit in the mould and a main portion of same extends from the slit so as to form a narrow cut in the tyre.
  • a wing, or a pair of wings, attached to said end portion is received in a hollow in the slit and a wedge belonging to the wing itself is able to force the wing to a locked condition while the lamella is being fitted into the slit.
  • a thin frangible portion or a pair of frangible portions keep the wedge attached to the wind and break to enable movement of the wedge and obtain locking when the lamella is being fitted in the slit.
  • the wedge is previously positioned in a housing in the hollow and the wing portions move to the locked condition when they come into contact with said wedge.
  • Document EP1719598A1 shows a method of fastening a lamella to a mould for tyres.
  • a groove is formed in the mould.
  • the groove has a straight guide portion facing up on the inner surface of the mould as well as a portion of greater width formed more deeply and connected to the guide portion by a step.
  • the lamella at one end designed to be inserted into the groove has a bent portion that when the lamella is pushed into the portion of greater width, is snap engaged with the step.
  • Patent JP60097811 discloses a mould for tyres comprising a ring mounted within a support body of the mould, which ring has a shape matching that of the tyre to be vulcanised and moulded, and a plurality of lamellae.
  • the ring is provided with through openings having different shapes and the lamellae are each inserted and welded in a respective through opening.
  • the ring is installed on the support body through bolts.
  • Document WO 03/002334 A1 discloses a mould surface, for the provision of a profile tread of the tyre, with at least one slot-shaped cut-out.
  • a lamella for providing the profile tread for the tyre is inserted into at least one of the cut-outs.
  • the lamella projects over the opening mouth of the cut-out, out of the cut-out.
  • the lamella exhibits in its section inserted into the cut-out at least one laterally protruding part piece, of which the side turned towards the opening mouth runs at a distance from the opening mouth, whereby, arranged between the side of the part piece turned towards the opening mouth and the opening mouth itself, is a fixing element connected to the side wall of the cut-out.
  • Document JP 03 264308 A discloses a segment of a mould provided with knife blades projecting from an inner peripheral surface.
  • the knife blade comprises a U-shaped built in section having a base section and two wings sections inserted into a U-shaped channel.
  • the Applicant has also noticed that the fastening methods of the known art do not allow the correct extension of the lamellae beyond the inner surface of the mould to be set in a precise and repeatable manner and, as a result, also the depth of the narrow cuts or sipes made on the tyre tread cannot be accurate and of sure repetition.
  • the Applicant has observed that known lamellae all rest on an inner surface of the seat in which they are installed and, therefore, the amount of the lamella portion projecting from the mould surface depends on the precise working of said seat. On the other hand, working of said seat so as to obtain close tolerances is difficult and expensive and adversely affects the production costs of the mould.
  • the Applicant has examined the problem of efficiently connecting each lamella to the mould in such a manner that the lamella does not separate therefrom during an important part of the useful life of the mould itself, but without introducing complications in the production process of the mould.
  • the Applicant has also examined the problem of ensuring the correct positioning of each lamella in order to enable it to project from the mould surface by a predetermined correct amount.
  • each lamella in such a manner that it has an abutment surface designed to bear against the inner surface of the mould and at least one lug or tab adapted to be inserted and locked by means of addition material into a respective seat formed in said inner surface, it is possible to simultaneously ensure safe locking of the lamella and correct height of same.
  • the present invention relates to a vulcanisation and moulding apparatus according to claim 1.
  • the present invention relates to a method of manufacturing a vulcanisation and moulding apparatus for tyres according to claim 14.
  • the correct measure of the lamella height is obtained in a precise manner through working of the abutment surface belonging to the outer work portion of the lamella and of the inner surface of the mould, without being obliged to operate with close tolerances at the inside of the slit housing an engagement portion of the lamella itself. In fact said engagement portion has not to abut against the slit bottom.
  • the lug or lugs keeps/keep well visible at the sides of the work portion and can be easily reached by suitable tools adapted to lay the addition material thereon.
  • the present invention in at least one of said aspects, can further have one or more of the preferred features hereinafter described.
  • said at least one lug lies in a recessed position relative to the inner surface and together with the seat delimits a laying cavity for the addition material.
  • the cavity allows a sufficient amount of addition material to be laid so as to ensure steady locking without this material generating protuberances on the inner surface of the mould. These protuberances would produce corresponding recesses on the tyre tread. In fact, after laying of the material, a smoothing action can be carried out on the region with the addition material.
  • said abutment surface is spaced apart from said at least one lug by a distance measured along the insertion direction.
  • Said distance is the depth of the laying cavity.
  • said distance is greater than or equal to about 0.3 mm.
  • said distance is smaller then or equal to about 1.2 mm.
  • said distance is greater than or equal to about 0.5 mm.
  • the lug inserted in the seat is in a recessed position relative to the inner surface.
  • said at least one lug extends along a direction orthogonal to the insertion direction over a length greater than or equal to about 2 mm.
  • said at least one lug can extend along a direction orthogonal to the insertion direction over a length smaller than or equal to about 10 mm.
  • said seat is a slit and the lug has a laminar shape.
  • said slit has a width greater than or equal to about 0.3 mm.
  • said slit can have a width smaller than or equal to about 1.2 mm.
  • said lamella comprises two lugs positioned on opposite sides of the lamella.
  • Anchoring on opposite sides ensures a more efficient locking and a greater steadiness of the lamella.
  • Said lamella can comprise a portion for engagement with the inner surface inserted in a respective groove formed in the inner surface and opening on said inner surface, said engagement portion and respective groove being aligned relative to the work portion, along an insertion direction of the lamella in the seat.
  • the lamella is located in the mould surface not only at the lug or lugs, but also at an engagement portion aligned with the work portion.
  • said at least one lug extends starting from the engagement portion.
  • the groove and seat are defined by a single cut.
  • the engagement portion extends away from the abutment surface along the insertion direction over a distance greater than or equal to about 2 mm.
  • the engagement portion can extend away from the abutment surface along the insertion direction over a distance smaller than or equal to about 4 mm.
  • the lamella preferably, consists of a cut-off and bent sheet metal. Therefore, manufacture of the lamellae according to the invention is simple, quick and cheap.
  • the lamella is made of steel.
  • the lamella is very strong and does not bend or break under the pressure exerted by the elastomeric material during vulcanisation/moulding.
  • the containment walls are made of aluminium. Since aluminium can be easily worked, the moulds can be made more quickly and in a more precise manner. Furthermore, the thermal conductivity of aluminium positively affects the vulcanisation process.
  • the addition material can consist of metal material.
  • the addition material is aluminium.
  • the lamellae made of steel can be safely joined to the mould made of aluminium even if the two materials (aluminium and steel) cannot be joined together by a traditional welding process.
  • the step of inserting said at least one lug comprises the step of bringing said at least one lug to a recessed position relative to the inner surface, so as to delimit, together with the seat, a laying cavity for the addition material.
  • the step of providing each lamella comprises the steps of cutting off a shaped portion from a sheet metal and bending at least one part of said shaped portion to form said at least one lug.
  • the step of providing each lamella comprises the steps of cutting off a shaped portion from a sheet metal and bending two parts of said shaped portion to form two mutually spaced apart lugs.
  • the two parts are bent towards opposite surfaces of said shaped portion.
  • said part of said shaped portion is bent according to an angle greater than or equal to about 45°.
  • said part of said shaped portion is bent according to an angle smaller than or equal to about 135°.
  • the angle is such selected as to space apart the lug from other parts of the lamella as much as possible, so as to minimise the thermal interference between the different steel portions during laying of the addition material.
  • the cutting-off step comprises the step of making at least one recess in the shaped portion in order to define said at least one part and said at least one abutment surface; the part and abutment surface being spaced apart by a distance measured along an insertion direction of the lamella into the seat.
  • the method contemplates the seat being made in the form of a slit.
  • laying of the addition material is made by laser welding.
  • laying of the addition material is obtained by TIG (Tungsten Inert Gas) welding.
  • addition material is a metal material.
  • the addition material is aluminium.

  • Shells 4 each comprise a work surface 5 designed to operate on the beads 6 and sidewalls 7 of a green tyre 2 to be vulcanised.
  • Shells 4 disposed mutually close to each other in said equatorial plane "P" further define a circumferential surface 8 designed to operate against a tread band 9 of tyre 2 to be vulcanised.
  • apparatus 1 is of the type consisting of sectors.
  • Each of the two shells 4 comprises a plate 4a carrying the work surface 5 and a plurality of circumferential sectors 10 that can be separated from plate 4a and carry half of the circumferential portion 8.
  • the circumferential sectors 10 together with plates 4a define containment walls of the moulding cavity 3.
  • apparatus 1 is of the type made up of two halves, i.e. each of shells 4 consists of a single body and therefore defines one half of apparatus 1.
  • An inner surface of each of the two shells 4 comprises the work surface 5, designed to operate on the beads 6 and sidewalls 7 of the green tyre 2 to be vulcanised, and half of the circumferential portion 8 operating on the tread band 9 or tyre crown.
  • the containment walls 4a, 10 comprise an inner surface 11 defining a moulding cavity 3 the shape of which matches the final conformation to be given to tyre 2.
  • the containment walls 4a, 10 are made of aluminium or steel.
  • the green tyre 2 once enclosed in apparatus 1, is pressed against the containment walls 4a, 10 by a suitable device 12 defined by a bladder for example. Subsequently or simultaneously with the pressing step, heat is supplied to tyre 2 pressed against the containment walls 4a, 10.
  • suitable ridges provided on shells 4 cause formation of a desired tread pattern on the tread band 9 of tyre 2, as well as possibly formation of graphic signs on the sidewalls 7 of the tyre 2 itself.
  • the supplied heat causes cross-linking of the elastomeric material of which tyre 2 is made.
  • the vulcanised and moulded tyre 2 is removed from apparatus 1 after opening of the latter.

  • Each lamella 13, as better shown in Fig. 2 has a work portion projecting from the inner surface 11 and is adapted to form a corresponding lamellar cut or sipe on the vulcanised tyre 2.
  • the work portion 14 lies in one or more planes orthogonal to the inner surface 11.
  • the sipes are preferably disposed consecutively close to each other in a circumferential direction and oriented substantially transverse to the rolling direction.
  • the task of these sipes is substantially to efficiently receive and retain the snow during rolling of the tyre, since it is known that snow-to-snow friction is greater than rubber-to-snow friction.
  • the lamellae 13 are disposed in circumferential parallel rows.
  • the lamellae 13 of each row are arranged consecutively close to each other in a circumferential direction and oriented in a way substantially transverse to the equatorial plane "P".
  • Fig. 1 shows the lamellae 13 of all circumferential rows visible in a radial section of apparatus 1, each of said lamellae 13 being disposed in a respective block of tyre 2.
